Jay again you have provided awsome info. I almost hate to go here but I'd feel bad not throwing this on the table for consideration. Since you are runing a low riser based CJ Head
CJ/LR Head============================ 2.34" x 1.34"
vs
Edelbrock Heads =================@ 2.13" x 1.42"
and the factory Med Risers====== @ 2.06" x 1.38"
AND from the LOL Dept.
Street Master ==================1.76" x 1.06"
Can I add Edelbrock Head Port is 3.02 Square Inches and the Street Master is 1.86 Square Inches!!!!!!!!!!!!
By port matching the intake manifold runners are you not at least altering any future tests and or potentially optimum use of the tested intakes with the Med Riser based heads? Im other words "Measure twice and cut once" Are you sure you want to go in that pretty hard to reverse direction for the "information" you will derive?
